Multifunctional capillary viscometer

The utility model discloses a multifunctional capillary viscometer; the multifunctional capillary viscometer comprises a capillary viscometer body, wherein the capillary viscometer body is composed of a liquid charging pipe, a capillary, an exhaust pipe and a U-shaped guide pipe; the U-shaped guide pipe is communicated with the lower pipe mouths of the liquid charging pipe, the capillary and the exhaust pipe; the capillary viscometer body is arranged in a transparent insulation heating sleeve in a sealed manner; a liquid inlet pipe joint and a liquid outlet pipe joint are arranged on the upper and lower side walls of the transparent insulation heating sleeve; the upper pipe mouth of the liquid charging pipe is shaped as a horn mouth; a liquid discharging pipe is downwardly arranged at the bottom of the U-shaped guide pipe; the liquid discharging pipe extends out of the bottom wall of the transparent insulation heating sleeve in a sealed manner; and a liquid discharging valve is arranged on the liquid discharging pipe outside the transparent insulation heating sleeve. The multifunctional capillary viscometer disclosed by the utility model has the advantages that the structure of the existing capillary viscometer is improved; therefore, the disadvantage caused by the demand for a constant-temperature water bath in the event of measuring the viscosity and the problems of being difficult to charge liquid and clean in the existing capillary viscometer are solved; and particularly, the multifunctional capillary viscometer has the more prominent advantage when the viscosity of liquid to be measured is higher.
